6 Tips to Beef Up Your Mac Security

April 13, 2017

Though more secure than other systems, Macs also have chinks in their security. Mac user base has grown considerably over the past few years, making it profitable for hackers to target the systems. That is why it is important to beef up your Mac’s security with proven tools such as iDoctor that also feature Mac hard disk cleaner. iDoctor app provides online and offline security and features a range of tools that help identify, eliminate, and keep away potential threats, including Mac cleaner. To help, we discuss other steps you can take to enhance your system’s security. Take a look.

1. Back up Data With Time Machine

Time Machine is a backup software application distributed exclusively with Mac OS. It creates backup files (for the entire system) and saves them on an external hard drive. These files can be restored at a later date. Time Machine creates hourly backups for the last 24 hours, daily backups for the last month, and weekly backups for older data. When the system runs out of free disk space, it frees some by deleting the oldest weekly backup first. Time Machine supports a select few configurations that include a hard drive connected to the computer, drive shared by an AirPort Time Capsule (wireless router sold by Apple), or local network volumes that use Apple Filing Protocol to connect.

2. Disable Java and Flash Plug-ins

Java plug-ins are not designed to run any security checks before running a content, often exposing the system to malware attacks. Security experts, therefore, advise that you disable Java, and plug ins. Moreover, most sites today use HTML5, and you would rarely need Java when browsing the internet. To disable Java on your Mac system, go to the Applications folder, click on the General tab, and uncheck all the Java boxes. Configure settings using your Chrome or Firefox browser to disable Flash.

3. Use Firewalls

OS X, like other systems, has an in-built firewall that offers limited protection against malware and allows applications to establish external connections without any restrictions. You can beef up your system’s security by downloading Little Snitch, an advanced firewall for Mac systems that allows users to control connections between the Internet and their system. Version 3 of the firewall includes an “Automatic Profile Switching” feature that helps apply different rules depending on the network. Little Snitch performs a range of roles and informs you whenever an app is trying to establish an external connection. Taking prompt action whenever you get such notifications can help you avoid data theft, as there’s a chance that the app may be trying to transfer personal info to an external destination. The firewall also handles different interphases, including AirPort, PPP, and network cards and blocks untrusted IP addresses.

4. Activate Keychain

Using the same password for multiple accounts can provide a window of opportunity for hackers to sneak into the system and steal vital personal and business info. To avoid this problem, use different passwords for different accounts. To help you remember all the passwords and other relevant info, OS X’s password manager, Keychain, stores passwords, certificates, and other important info. To set up keychain on your Mac, select iCloud pane under system Preferences. Next, choose the Keychain checkbox and insert your Apple ID and password. The system will then direct you to create an iCloud security code and you will be required to enter your phone number to receive a confirmation SMS.

5. Disable Automatic Login

Automatic login is preferred by many users as they don’t have to enter their password every time they want to log into their system. Automatic login, however, has a major downside as it makes it possible for anyone to access your system . To turn off automatic login, go to System Preferences and select Users and Groups. Select the lock icon on the left hand corner of the screen and enter the admin password.  Select Login options, and click on ‘off’ in the drop down menu.

6. Use File Vault to Encrypt Files

File Vault was first introduced by Apple in 2003, and is an on-the- file encryption scheme that aims to protect user data. File Vault enables you to encrypt files in the user account. To decrypt the files, you’ll need to enter your account password or use the recovery key. Before switching on Filevault, remember to backup your data. To enable FileVault on your system, go to  ‘System Preferences’. Click on the ‘Security and Privacy’ tab, under which you can locate ‘FileVault’. Enter your password to turn on FileVault.
